I started the new blood thinner 3 weeks ago. Within the last week, I noticed that I was losing copious amounts of hair. It is distressing to see a huge pile of hair come out after showering and combing my hair. I have extremely thick hair, so much so that hair stylists occasionally thin it. It probably looks normal to everyone else, but I feel like I've probably lost at least 10% of my hair--much more than when I've gotten it thinned. 😠It turns out hair loss is a common side effect of some blood thinners. I didn't have this problem with Lovenox or Eliquis, so I had no idea to be on the lookout for it. After consulting with my hematologist, I am back on two shots a day of Lovenox. He thought it was too risky to try Eliquis again (I took this pill last year, and a month later I was back in the hospital with recurring blood clots). It is very disappointing to go back on Lovenox, but I can handle the 2 shots a day. I'm more distressed about how much longer I'm going ...
